On 91 these are good for quite a bit, but on E85 they run out faster. I asked mellon on their "what size injector thread" when I was planning on running a red and these would prob be maxed out then on E85. So i'm not sure what horsepower range but these should be good on stock turbo, fp green, and probably fp red depending how much power you want to make.
